mousewheel event issue

[Anna]

I wanted to use mouse scroll event . I tried " mousewheel " but its giving me an error " TypeError: eventTypes is undefined". Can smeone please help me here!!!!!!!

[obiot]

would help if you could be a bit more descriptive....  which version of melonJS, which browser, which platform ?

also a code snippet would be great

 

 

[obiot]

also if possible try to use the title of the post to give a short description of the message, to avoid having all messages titled "melonJS"

 

thanks !

[Anna]

okay. I will be more descriptive with the title next time.!!!

I am using melonjs 4.1 . Tried in both firefox and chrome, I am using Windows 8.1

 

this is my code 

      me.input.registerPointerEvent("mousewheel", me.game.viewport, function (event) {
           me.event.publish("mousewheel", [ event ]);
       },false); 
        this.mousewheel = me.event.subscribe("mousewheel", function (event) {

   
            var viewport = me.game.viewport;
            viewport.currentTransform.translate(
            viewport.width * viewport.anchorPoint.x,
            viewport.height * viewport.anchorPoint.y
          );
           
            viewport.currentTransform.scale(0.995);
            viewport.currentTransform.translate(
            -viewport.width * viewport.anchorPoint.x,
            -viewport.height * viewport.anchorPoint.y
         );
           

          
        });

oops, looks like you found an issue with the 4.1.0. We did refactor some code linked to pointer event management, and it seems that we kind of broke the mouse wheel event.

I just fixed it on the master branch, if you pull the latest version it should work then (i tested using your code snippet).

Sorry about that, and thank you 10000x for reporting it

[obiot]

to be noted that 4.1.0 is not released yet, master is our current development branch, so issues are to be expected  just saying in case you stumble on something else

Should i just add the pointer.js file you have updated??? I cdnt find the latest melon.js file in the github .

Thankyou so much.. Mousewheel event is working for me now  . but is there a way to differentiate mouse scroll up and mouse scroll down. for example i am trying to zoom in and zoom out using mouse scroll.

[obiot]

yes, in the event object you can check the `deltaY` property

[Anna]

got it  Do u have any example for panning as well??
